ACDS-1001 Automotive Air Quality Sensor for Carbon Dioxide Measurement

The ACDS-1001 is an in-cabin air quality sensing array specifically designed for the automotive industry. An integrated particulate matter and NDIR carbon dioxide sensor measure these critical air quality parameters in real-time and then communicates directly to the vehicle controller via a CAN, LIN or J1939 interface
Target applications for the ACDS-1001:
● Child Left Behind Detection
● EV HVAC System Optimization for Battery Driving Range Management
● Driver Alertness Monitoring
● Cabin Air Quality Monitoring & Improvement
